Stigmina
Stigmina is a genus of fungal plant pathogens in the family Mycosphaerellaceae, established by Saccardo in 1880. Species in this genus cause leaf spot diseases on a wide range of woody hosts, including conifers and broadleaf trees. The genus is characterized by superficial sporodochia that develop through stomata, with conidiophores arising laterally from the lower outer cells. Transmission occurs primarily via airborne conidia.
